Scientists Created A 3-D Hand That Unlocks Fingerprint Scanners

Recreating a 3-D replica of once hand with fingerprints is now possible, reports claim.

Anil Jain from Michigan State University created this to inform security companies that this can happen. Jain and his team created a life-size 3-D hand model using a high-resolution printer to be test fingerprint scanners.

The researchers explained that this is the first time a 3-D hand with fingerprints was created. They explained that with the use of this technology people can still a person's identity, Science Daily reported.

However, they also believe that this will allow security companies to test their fingerprint scanners. This will allow security companies to create more secure finger print scanners.

They also agree that this will not only benefit security companies but will also benefit government offices like the FBI, CIA and military.

The researchers studied this because they want a standardized calibration for all fingerprint scanners used in airports, police departments and banks. They want a more realistic hand representation that's better than the 2D representations that are currently used, Quartz reported.

They explained that 2D representations do not give adequate simulation on the user-scanner interaction. They said that 2D representations can't emulate fingerprints.

For this study, they used a high-resolution 3D printer that can create ridges like a real finger. They stressed that the material they used is as thick and elastic as the human skin.

After that, they created a glove-like hand that a person can wear on his hand. This can be used at slap scanners to capture fingerprints.

Upon testing, the researchers found out that light-colored materials used in the hand works better than dark materials. They also found out that the hands should be coated with conductive ink, silver and gold, to work properly on cellphone scanners.

Last July, the researchers used their technology to unlock a murder's victim phone by creating a replica of the victim's finger.
